Before deleting this filesystem, You must delete shares referencing this filesystem

Hi There,

i setup a zfs pool , mirror with two internal sata drives.

This was just a test on my part, as i know both of these drives have smart errors.

I have now purchased new disks, and wanted to remove the zfs filesystem from omv, before i removed the faulty disks, and installed the new disks.

i removed both my nfs & smb shares first, no problems there.

but when i try to remove the filesystem, i get this error :

Error #0:exception 'OMVModuleZFSException' with message 'Before deleting this filesystem, You must delete shares referencing this filesystem.' in /usr/share/openmediavault/engined/rpc/zfs.inc:292Stack trace:#0 [internal function]: OMVRpcServiceZFS->deleteObject(Array, Array)#1 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#2 /usr/share/php/openmediavault/rpc/rpc.inc(84): OMV\Rpc\ServiceAbstract->callMethod('deleteObject', Array, Array)#3 /usr/sbin/omv-engined(516): OMV\Rpc\Rpc::call('ZFS', 'deleteObject', Array, Array, 1)#4 {main}

I have tried rebooting the system after deleting the shares, but i still get the above error message.

i then also tried removing the filesystem with :

zfs destroy -f zfs_mirror

did not give me any error messages , but my filesystem is still there :

root@pgnas2:~# zfs list
NAME USED AVAIL REFER MOUNTPOINT
zfs_mirror 7.95G 1.75T 7.95G /zfs_mirror

Any help is very appreciated!

Thanks for the reply.

I removed the entry in /exports
removed the entry in /fstab

But not sure what to remove in config.xml

i might just remove the whole plugin and try again.

removing and re-installing the plugin did not work

Hi,

Many thanks, please find attached my config.xml

Hi,

Many thanks for helping out!

i replaced my config.xml with your modified version and rebooted.

the zfs pool is still visible in OMV , but now when i go into the zfs section, i get a prompt that i have to apply the new settings.

when i click to apply the settings, i now get :

Error #0:exception 'OMV\ExecException' with message 'Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; mount -v '/zfs_mirror' 2>&1' with exit code '1': mount: can't find /zfs_mirror in /etc/fstab' in /usr/share/php/openmediavault/system/process.inc:175Stack trace:#0 /usr/share/php/openmediavault/system/mountpoint.inc(135): OMV\System\Process->execute()#1 /usr/share/openmediavault/engined/module/fstab.inc(71): OMV\System\MountPoint->mount()#2 /usr/share/openmediavault/engined/rpc/config.inc(189): OMVModuleFsTab->startService()#3 [internal function]: OMVRpcServiceConfig->applyChanges(Array, Array)#4 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#5 /usr/share/php/openmediavault/rpc/serviceabstract.inc(150): OMV\Rpc\ServiceAbstract->callMethod('applyChanges', Array, Array)#6 /usr/share/php/openmediavault/rpc/serviceabstract.inc(528): OMV\Rpc\ServiceAbstract->OMV\Rpc\{closure}('/tmp/bgstatuskq...', '/tmp/bgoutputyy...')#7 /usr/share/php/openmediavault/rpc/serviceabstract.inc(151): OMV\Rpc\ServiceAbstract->execBgProc(Object(Closure))#8 /usr/share/openmediavault/engined/rpc/config.inc(208): OMV\Rpc\ServiceAbstract->callMethodBg('applyChanges', Array, Array)#9 [internal function]: OMVRpcServiceConfig->applyChangesBg(Array, Array)#10 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#11 /usr/share/php/openmediavault/rpc/rpc.inc(84): OMV\Rpc\ServiceAbstract->callMethod('applyChangesBg', Array, Array)#12 /usr/sbin/omv-engined(516): OMV\Rpc\Rpc::call('Config', 'applyChangesBg', Array, Array, 1)#13 {main}

Ok many thanks, will try that
